rnvinc, great post. This thread has been dead for a while. I appreciate the update. I am personally disappointed with the concept that it will take 3 dang years to evaluate the effectiveness of this ''Accustic Fence' but I guess it takes this long for the people we have working here in KY to figure this out. I guess they will mark the areas off as no fishing areas, but don't know. You would think that KY dam would need the same survey since the carp should also be there below the dam, but I guess 1/2 of the info is better than nothing. I hope we have 3 years to figure out the problem.
